Ok, thanks a lot for the info. I didn't know that. When I bought my Poulan, I opted for the 42cc as I mistakenly thought the only difference was in the carb mounting and I opted to buy the 42cc to stay away from that. Now, both for more power and a lighter engine, I wish I had gotten the 46cc. Not that big a deal really to come up with a carb mount... Oh well, the 42cc has about the same power as a Fuji 43cc without me doing any mods to it and it flies the Giant Stik very well, so I'm not going to change anything now.

Thanks again,
